JOHN W. WURTS, OF ELYRIA, OHIO.

HEATING SYSTEM.

Application filed October 9, 1317.

To all whom it may concern:

Be it known that 1, JOHN V. WUn'rs, a

'citizen of the United States, residing at lyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Heating Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to heating systems useful, for example in connection with the heating of a set of rooms or apartments, and has for its object improvements in the heating systems now in use, whereby a cold room may be more quickly heated to a suitable temperature, or the air in a room quickly changed for warm, fresh air.

The particular objects of my invention and the invention itself will be understood from a description of an embodiment of my invention.

Figure 1 is a general view of a heating system showing an embodiment of my invention.

Fig. 2 shows an alternate means for con-- trolling the air from and to the apartment A.

Referring now to the drawing and to the embodiment of the invention shown therein, at A, A and A are shown a set of rooms or apartments, which may be placed in communication through the use of doors B and B. It will be understood that any number of rooms or apartments may be in the set or may be placed in communication through doors, windows, or otherwise, as desired. At G is shown a furnace whichmay be of any suitable form. In the embodiment shown the furnace C is provided with a fire box D and with an air cell E. The products of combustion are discharged through a pipe F.

A duct is shown at G which will here be spoken of as the first duct, and which communicates at one end 8 with the room A, and at the other end 4 with the air cell E. Better results are secured by connecting the end 4 of the duct G to the air jacket near the bottom thereof. Any suitable form of intake or exhaust for air may be used as shown at 5. A second duct is shown at H, placing the chamber A in communication with E, and which here connects at one end 7 with the duct G and at the other end 8 Specification of Letters Patent.

with the air cell placing the duct G and chamber E in communication. To secure the best results, the duct H is connected to the air cell E at a point above the connection of the duct G thereto. In the embodiment shown, the duct H is connected at 8 near the top of the air jacket.

At J is shown a third duct which is pro.- vided for supplying cold air to the furnace. This duct connects at one end 10 with a suitable source of cold air, such as a room or apartment, or the outside of the house, and leads to the air cell E, being preferably connected at a point 11 near the bottom thereof.

A fourth duct is shown at L, which is connected at one end with the air jacket and leads to the rooms A and A. I prefer to connect the duct L to the jacket at a point 12 above the points 4 and 11. Means are provided for opening either the first or the second duct and closing the other. In Fig. 1 this means comprises two dampers or valves M and N. M is placed in the duct G between 7 and 4: and N is placed in the second duct between 7 and 8.

The operation of the system is as follows: If the room A is cold and it is desired to heat it quickly, the damper M is thrown open and the damper N is closed. The cold air is then drawn from the room A through the duct G to the bottom of the furnace, where it is heated and distributed through the duct L to the remaining rooms in the house. When this operation has been in progress a suflicient time, and generally a short time is sufficient, as I have found by experiment, the damper M is closed and the damper N is opened, whereupon hot air is immediately supplied to the room A through the duct H and the portion G, of the duct G. Under normal conditions cold air is drawn in through the duct J heated and supplied to the various rooms of the set through the ducts H, L and the portion G of the duct G. Of course said air may be drawn into E through J and G simultaneously.

In Fig. 2 I have shown a single damper or valve at O, which is hinged at 0 and which may be positioned at 0-0 across the entrance to the duct H or at 0-0" across the entrance to the portion G of the duct G. I prefer to connect a chain 79 to the damper O to control the same. A hook q is provided on the wall or some other stationary object to cooperate with the hook r to hold the damper O in the position 00. The damper may be weighted, as shown at s so that it will normally take the position o-0 when the chain is released.

Of course, when the damper is in the position o--0 cold air will be drawn from the room A, and when the damper O is in the position 00 hot air will be furnished thereto. I have found by actual experiment that by the use of. my invention I can very quickly heat a cold room. The advantage of this system, in general, will be appreciated, and in addition, there is a special advantage where it is desired to keep a room cold and then suddenly heat it, such for example, as the bed rooms of those who sleep with the windows open and who desire to heat them quickly in the morning.

It will be seen that I may quickly withdraw the foul air from a room by opening the portion G of the duct G and closing the duct H. This is especially advantageous where it is desired to empty a bed chamber at bed time and replenish it with fresh air, though, of course, the air in any room may be quickly exchanged for warm, fresh air at any time.

The device 5 may be placed at any convenient place in the room, either the floor, the ceiling or the side walls. The furnace may be placed at any suitable location, preferably in the cellar of the building whose heating it controls. The chain p may lead to any convenient place, such, for example, as to the room A.

I have shown this embodiment and these details for the purpose of describing my invention. It will be apparent that departures may be made both from the form and details without departing from the spirit of the invention.

I claim In a heating system, the combination of' a furnace for heating air provided with an air jacket thereabout, a first duct communicating' with one of a set of rooms or apartments at one end and connected at the other end near the bottom of the air jacket into which it opens, a second duct opening at one end into the air jacket near the top thereof and at the other end into the first duct, means to close either duct and open the other, a third duct placing said air jacket in communication with a source of cold air connected to the air jacket near the bottom thereof and a fourth duct connected to the air jacket near the top thereof and placing said air jacket in communication with all the other rooms or apartments of said set than the room withwhich the first duct communicates.

In witness whereof, I have hereunto signed my name this 28th day of September, 1917.
